Use this Promotion to Enter Best Ball Mania for Free

The top prize for Underdog’s 2024 Best Ball Mania contest is $1,000,000, which puts them way ahead of the largest prize ever offered by FanDuel or DraftKings for a best-ball contest. For a company that built a great product and built it slowly, this contest is a great way for the Underdog app to finally get the attention it deserves.

The best part about this contest is that every new player that makes a $10 deposit (or more) can enter for free. Simply use the Underdog Fantasy promo code ROOKIE when you register, then cash in your store credit on a 2024 Best Ball Mania entry!

What Makes Underdog Our Top-Rated DFS App for 2024?

There are plenty of reasons to download the Underdog Fantasy app beyond just the great new player promo offers. Underdog was built by the same team that developed the Draft App which was acquired by FanDuel prior to the 2020-2021 NFL season. They clearly brought their past experiences into this daily fantasy sports platform project, and we think developed a product that even exceeds what they built at Draft.

Starting with the app, users are blown away by how sleek the design is, how easy it is to use, and how well laid out every contest type is (including their Best Ball Contests). Finding and entering a best-ball draft is extremely straightforward, and the player pool is large enough that drafts constantly fill.

Beyond having arguably the top best ball product in the market, Underdog’s pick’em contests offer one of the better stat-style DFS options available. Simply select the game you want to place an entry on, choose a player to place an entry on and whether you think they will go higher or lower a particular stat total, and choose your entry size. Win up to 10x your entry in these pick’em contests.

What About the Underdog Sportsbook?

Leveraging its success in the DFS market, Underdog is also venturing into the sports betting industry in North Carolina for those 21 and older.

This is a new market for the king of DFS, but we think they’ll hold their own. If its NC online sportsbook is anything like its DFS platform, it will offer a comprehensive bet selection and a smooth-running app. 

We’re going to get our hands on the app and give it a shot, but until then, North Carolina residents should take advantage of their current sportsbook-only bonus offer.

Differences Between Underdog Fantasy and Other DFS Platforms

When you’re on the fence about which fantasy sports contests to get into, you must understand the difference between them.  Underdog Fantasy stands out from other DFS platforms in several significant ways—

  • Unique game formats. Unlike traditional DFS sites primarily using a salary cap model, Underdog Fantasy focuses on snake draft formats and best ball contests. This means participants draft their teams live, similar to season-long fantasy sports but without the need for ongoing management.
  • Stat-style contests. Underdog also offers “pick ’em” contests like stat-based DFS sites. These games allow players to predict performance, adding another layer of strategy and excitement.
  • Large prize pools. Underdog Fantasy is known for having some of the largest best ball contests in the industry. This is easily our favorite part of Underdog Fantasy.
  • User Experience. The platform has been praised for its clean app interface and built-in draft tools, which are accessible all year round.

Other platforms like DraftKings and FanDuel use a salary cap model where users have a fixed budget to create their team. PrizePicks offers more options than any other DFS app with stat contests, and Thrive Fantasy is known for better odds.

What We Love the Most About Underdog Fantasy

Several aspects of Underdog Fantasy make it a standout in daily fantasy sports. Having been a player on the platform since its earliest days in March 2020, a few things make it one of my favorite DFS platforms.  You might not agree with all of these, but everyone loves Underdog for their own reasons.

  • Unique Game Formats: The focus on snake drafts and best ball contests provides a refreshing change from the traditional salary cap model used by many DFS platforms.

  • Stat-Style Contests: The ‘pick ’em’ contests add an extra layer of strategy and anticipation to the game, as players predict performance stats.

  • Large Prize Pools: Underdog Fantasy is known for offering some of the largest best ball contests in the industry. It’s always exciting to play for big stakes!

  • User Experience: The clean interface, intuitive design, and built-in draft tools make using the Underdog Fantasy app a breeze, whether you’re a seasoned player or a newcomer to DFS.

  • High-Profile Investors: With big names like Mark Cuban and Kevin Durant backing the platform, it’s clear that Underdog Fantasy is poised for big things in the future.

Can I use the Underdog Fantasy promo code more than once?

Can I share the Underdog Fantasy promo code with friends and family?

What is Underdog Fantasy’s Best Ball?

Of all of the Underdog Fantasy contests, Best Ball is one of the most popular and exciting. Underdog Fantasy Best Ball is a popular format for fantasy sports where entrants select players through a snake draft. Once the draft is complete, the participants are not required to manage lineups. Underdog Fantasy’s platform automatically chooses the highest-scoring players on your roster every week to calculate your score for the week. The team with the most fantasy points wins.

How is Underdog Fantasy different than legal sports betting?

Legal sports betting sites like DraftKings Sportsbook or FanDuel Sportsbook require participants to wager real money on the outcome of a game. Underdog Fantasy, on the other hand, focuses more on things such as player statistics and overall performance than any matchup’s actual outcome. It’s more in line with fantasy sports than sports betting. Underdog Fantasy also offers smaller prizes and is legal in more states.

Underdog Fantasy App Review

Underdog Promotions: Editor Review and Rating

With a product as new as Underdog, new players want to make sure they are getting the best deal when they register. So, how does this offer compare with the top DraftKings promo code offer for May? The review below compares Underdog’s current promotions directly to the best promotions in the industry.

Underdog offers a niche fantasy product that focuses on two contest types that are relatively ignored on the current version of the FanDuel and DraftKings apps. The app is arguably the best in the industry, the variety of contests is unparalleled, and their current bonus offer is our top-rated DFS promotion for 2024. You simply can’t lose playing on Underdog.

The current 4.9 (out of 5) rating is the highest we have ever given a DFS app and recommend anyone looking for a best ball or stat format fantasy app give Underdog a try first.

Underdog Fantasy Review Overview


We absolutely love everything about the Underdog Fantasy app. Nobody does daily fantasy snake drafts better than Underdog, and this season they have added even more ways to play with pick’em and rivalry contests. Try out any of these DFS formats for free with the current Underdog Fantasy promo code offer. Simply make the depsoit and Underdog will match it dollar-for-dollar.
